On Monday, Twitter was all in arms with reactions to the news that 2018's most googled fashion brand used materials in clothes that are "known to the state of California to cause cancer, birth defects, and other reproductive harm," according to a tag sewn into some of the garments.

Twitter users @Aziaani posted a photo of her new neon green bathing suit from the online retailer.

She asked her followers, "Did y’all know this tag is in Fashion Nova swimsuits?"

The warning label says, "This product can expose you to D i(2-ethylhexyl) phthalate, lead and cadmium," which are chemicals linked to deteriorating male reproductive health, according to theNational Library of Medicine.

The $34.99 bathing suit or "Water Sports Bikini" is sold out on Fashion Nova's website. It has a 5-star rating and 75 reviews.

The tag references the state's Proposition 65 which requires visible warnings for potentially dangerous chemicals. Enacted in 1986, the legislation was amended in 2018 to include a provision that requires companies to identify the specific chemicals used that prompt the warning.
